This invention relates to improvements in The improved tool'includesapair of slide" 2 wheelwright machines and more particularlysectionsBand.

Pivotally mounted on this pin 10An th r bject of the inventionis to proisa U shaped pawl 11, the bightportion of vide a rim compressor having means whereby which is adaptedfor engagementbetween the operable parts thereof may be retained in ithe teeth of th'erack 7. The inner end of the rim compressing iti isection 3 has a pin projection 12for disma Still another object of theinvention is to ption through "the slot 13 longitudinally provide a rimcompressorwhich because of -frmed in the section liand to'the pin 12 isits simple construction can be manufactured journaled the inner end ofawlever' which is so at a cost Within the economic demand of the Igenerally referred to by numeral i i. This public, v le-veryinconstruction consists ofa pair: of These and other objects of theinvention bars 1515 which have their outer ends dis will become moreapparent to the reader after posed laterally i and secured together asat considering the invention as described and 16.

Furthermore, the tool can be employed with equal satisfaction as anexpander for rims by moving the lever 14 in the opposite direction afterproper adjustment has been made.

Obviously certain changes in the specific shape, size, and materials maybe resorted to in the construction of thenovel tool Without departingfrom the spirit and scope of'the invention as claimed hereinafter.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent is 1. A rim tool comprising a pair of slidesections, a lever pivotally connected at one end to one section, an armpivotallyconnected at the outer end of the other secti onyadjustableconnecting means between the arm and the lever, a hook at the outer endof each section, arack and pawl fastener between said sections, saidfastener consisting in providing a slot in one section, a rackat oneedge of the slot, a connecting pin on the other section disposed throughsaid slot, and a pawl carried by said last mentioned section forengagement with said rack. I

2. A rim tool comprising a pair of slidable sections, a lever pivotallyconnected at one end to one section, an arm pivotally connected at theother end of the other section, adjustable connecting means between thearm and the lever,'a hook at the outer end of each section, a rack andpawl fastener between said sections, said fastener consisting inprovidinsz a slot in one section, a rack at one edge of the slot, aconnecting pin on the other section disposed through said slot, and apawl carried by said last mentioned section for eneasement with the saidrack, said pawl comprising a U-shaped member pivotally secured at itsends to thesaid section, the bightportion of said member being disposedthrough the slot for engagement with the said rack on the edge of theslot.

In testimony whereof I afiix my signature.
